  • 2. 

    The role of the Respitory System is to bring oxygen into the body.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The respiratory system is responsible for bringing oxygen into the body. It consists of organs such as the nose, trachea, and lungs, which work together to inhale oxygen from the air and deliver it to the bloodstream. This oxygen is then transported to cells throughout the body, where it is used for various metabolic processes. Therefore, the statement is true.

    Is this the correct pathway of food through the digestive system? mouth, esophagus, stomach, small intestine, large intestine, urethra, toilet

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given pathway of food through the digestive system is correct. Food enters the mouth, passes through the esophagus, and reaches the stomach where it is further digested. From the stomach, it moves into the small intestine where nutrients are absorbed into the bloodstream. The remaining undigested food then enters the large intestine where water is absorbed, and finally, the waste material is eliminated through the rectum and anus, not the urethra, into the toilet. Therefore, the answer is true.

    What tissue is only found in the heart?

    • Epithelial

    • Skeletal

    • Cardiac

    • None of Above

    Correct Answer
    A. Cardiac
    Explanation
    Cardiac tissue is the correct answer because it is the only type of tissue that is specifically found in the heart. Epithelial tissue is found in various parts of the body, not just the heart. Skeletal tissue is associated with the skeletal system, not the heart. "None of above" is not a valid option as cardiac tissue does exist and is unique to the heart.

  • 5. 

                                                      substance in the mouth contains enzymes that begins chemical digestion.

    Correct Answer
    Saliva
    Explanation
    Saliva is the correct answer because it is a substance in the mouth that contains enzymes which begin the process of chemical digestion. Saliva contains the enzyme amylase, which breaks down carbohydrates into smaller molecules. This process is the first step in the digestion of food in the mouth before it moves to the stomach for further digestion.

    What is a stimulus?

    • An action or change in bahavior that occurs as the result of a stimulus

    • An inborn behavior

    • A change in an organisms surroundings that causes the organism to react

    • A behavior that must be taught

    Correct Answer
    A. A change in an organisms surroundings that causes the organism to react
    Explanation
    A stimulus refers to a change in an organism's surroundings that triggers a reaction. It can be any external or internal factor that provokes a response from an organism. This response can be in the form of an action or a change in behavior. The stimulus can vary widely, such as a sudden loud noise causing a startle reflex or a change in temperature leading to an organism seeking shelter. Therefore, the correct answer is "a change in an organism's surroundings that causes the organism to react."

  • 7. 

    Which chamber of the heart pumps oxygen-poor blood to the heart?

    • Right Ventricle

    • Left Ventricle

    • Right Atrium

    • Left Atrium

    Correct Answer
    A. Right Ventricle
    Explanation
    The right ventricle is responsible for pumping oxygen-poor blood to the lungs. After receiving deoxygenated blood from the right atrium, the right ventricle contracts to push the blood through the pulmonary artery and into the lungs, where it will be oxygenated. This oxygen-rich blood will then return to the heart through the left atrium and left ventricle before being pumped out to the rest of the body.

    Rate this question:

  • 8. 

    What are the blood vessels that carry blood away from the heart?

    • Cappilaries

    • Veins

    • Arteries

    • Blood vessels

    Correct Answer
    A. Veins
    Explanation
    Veins are the blood vessels that carry blood away from the heart. They transport deoxygenated blood from the body's tissues back to the heart, where it can be oxygenated again. Unlike arteries, veins have thinner walls and contain valves that prevent the backward flow of blood. This allows veins to efficiently return blood to the heart, completing the circulatory system. Capillaries, on the other hand, are tiny blood vessels that connect arteries and veins, facilitating the exchange of oxygen, nutrients, and waste products between the blood and body tissues.
